Sub-elemental phase center control for high-resolution RF scene projection

A system for controlling an antenna phase center location of a projected scene using radio frequency (RF) signals, the system comprising:

• an antenna array configured to transmit the projected scene including a plurality of antenna phase center locations, wherein the antenna array comprises a plurality of antennas in an arrangement;
• and
• a controller operatively coupled to the antenna array, the controller including one or more processors and a memory coupled to the one or more processors,
• wherein the controller is configured to:
• determine antenna phase center location weightings corresponding to the plurality of antennas, wherein particular antenna phase center location weightings corresponding to a particular antenna are based on distances between perceived lateral positions of particular antenna phase center locations and an actual lateral position of the particular antenna,
• wherein the perceived lateral positions correspond to virtual positions where a receiver is configured to perceive a signal to be originating from,
• wherein each antenna has multiple antenna phase center location weightings for multiple antenna phase center locations;
• determine, for each antenna, the signal to be transmitted based on all of the antenna phase center location weightings for a set of antenna phase center locations as well as based on a magnitude of each antenna phase center location of the set of antenna phase center locations, wherein the antenna phase center location weightings are configured to shift the projected scene a shift distance that is less than an antenna pitch between the plurality of antennas;
• and
• direct a transmission of the signal via the antenna array, wherein the signal is a radio frequency (RF) signal.
